The rarest still-obtainable mount in WoW is widely considered Invincible's Reins, dropped by the Lich King on 25-player Heroic in Icecrown Citadel at roughly a 1% chance. Some players have run 300–500+ weekly kills without a single one. A few mounts are technically rarer, but they're retired — the Swift Zulian Tiger and the trading-card Spectral Tiger can't be farmed anymore, only owned by the lucky few who got them in time.
"Rarest" splits into two answers: the hardest mount you can still grind for today, and the mounts that are simply gone. Here's how the top contenders stack up.
Rarest mounts you can still farm
- Invincible's Reins — The Lich King, 25 Heroic (ICC). Arthas's undead steed, ~1% drop, one attempt per week per character.
- Ashes of Al'ar — Kael'thas Sunstrider, Tempest Keep. A fiery phoenix, low single-digit drop rate, weekly lockout.
- Reins of the Onyxian Drake — Onyxia's Lair. Iconic black drake, notoriously stingy drop.
- Deathcharger's Reins — Baron Rivendare, Stratholme. A classic sub-1% farm you can run daily.
- Mimiron's Head — Yogg-Saron (0 keepers), Ulduar. A robotic head that trails through the sky.
Which is the single rarest overall?
If you count mounts no longer in the game, the crown usually goes to the Swift Zulian Tiger and Swift Razzashi Raptor from old Zul'Gurub, removed in Cataclysm, or the Spectral Tiger from a rare TCG loot card. Very few accounts have them, and they can't be earned today at any effort level.
Among things you can actually chase, Invincible is the usual pick because it combines a tiny drop chance, a hard raid boss, and a strict once-a-week attempt — so bad luck compounds over months, not days.
How long does farming Invincible take?
There's no guaranteed timeline. At ~1% with one kill per week per character, many players go a year or more. Running the raid on multiple max-level characters each week is the main way to raise your odds, since every character gets its own weekly attempt.
Are the rarest mounts account-wide?
Yes. Once any mount drops for you, it's added to your account-wide Mount Journal and every eligible character can summon it. That's why farmers spread kills across alts — more weekly rolls at the same reward.
Grinding a sub-1% mount across dozens of weeks wears people down.
